Hello I have a wired connection "Ethernet". And the problem I have been having lately is not all the time but I will be plugged in surfing the net and or what not and all of the sudden It disconnects out of nowhere. I check the cable modem and the internet is still working the lights are still on etc. So I restart my computer with the ethernet cable still plugged in to the modem and then it comes back? But this is getting old why is it doing that? Is there an issue with my ehternet cable and or hopefully not my internal Ethernet port?

just to confirm a device connected by wifi - never disconnects - correct - its only the one pc connected by a cable that intermittently disconnects - is that correct

would you post the following tests when the internet is working OK, and then repeat ALL the tests when the internet disconnects.
Make sure you also indicate on the reply which tests are for what condition.

Please post back here the make and exact model of the router and if you have a separate modem, the make and exact model of the modem.

What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, Mcafee , AVG etc

------------------------------------------------------------------------ ipconfig /all
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

We would like to see the results from an ipconfig /all - post back the results in a reply here.

Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results into notepad and then automatically open the notepad and display on your screen.

Now all you need to do is copy and paste those results into a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will now be highlighted

From the notepad menu - choose Edit - Copy

Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
The results from the notepad should now appear in the forum reply.------------------------------------------------------------------------

For your information only
these tests will check various stages of the connection, the first ping test, ping default gateway checks to see if you still have a connection to the router.
The next two Ping google.com & Ping 209.183.226.152 tests the connection to internet. google is to test by name and the ping test using a number is checking that a connection exists without DNS.
these tests then confirm if there is a dns issue on the connection.

this is when it is connected. I have not been disconnected for awhile so i do not know how to do that test. hopefully that is just my Ethernet cable and not something internally of computer. But there is some of my results

Ok I think know what the problem is. It just went out on me again with ethernet cable stil plugged into it wired connection. It would not even do anything of saying connected Ethernet it would just be blank. It would work if I restardted the computer but why? Is there some hardware networking problem going on? I =t is under warranty for 2 years but would you recommend replacing that if that is the problem? I also did a test to see if the internet is still working so i did wireless internet on it and it is fine?

The problem I am wondering about is why does the computer need to be restarted sometimes for it to do a ehthernet cable connection? I am mean it will work for a long time being wired connection and then all of the sudden out of nowhere it will just drop?'

ok so right now i am connected on wireless internet that works on internet. If I restart computer the cable works connected wired. I did try another ethernet cable and it did not work as well.

So How do I do the test of ehthenet cable if all I can connect is just with wireless internet right now? Like I said if i restart computer it will work and work for a long time before it does not? I just don't understand why it does that.

so can u tell me what might be the problem? And also what is your opinion on the USB ethernet adaptor ones? I have high speed interent and work from home so I would need one if I was to do that could handle the speed and streaming and what not for business. If I was to do that. Like I said it is weird because if I restart the computer it will work fine the ethernet port. Can u please tell me what u believe is the problem?

------------------------------------------------------------------------Safemode with networking
with a cable connected from PC to router
check the cable - see if there is a light on the router associated with the cable port used , also check if you have a green/yellow light on the PC LAN port
- try safemode with networking
as the PC starts keep tapping F8 - a menu appears - choose safemode with networking - see if that works for a longer time------------------------------------------------------------------------
